[Q] Install Apps while rejecting certain permissions (sandbox-like/vm)?

Hi there! Is it possible to install an App and reject certain permissions?
E.g: an App wants to read/write my contacts, although there is obviously no need for it (e.g. a cookbook App)?
I know it's not possible out of the box, but is there a program like, say "superuser", that is able to block only certain permissions on installing an App? Of course with the possibility that this App will not work correctly then...
Like a virtual machine: you can install and test everything within it, while not giving it access to the host.
Is this something that isn't even possible because of the structure of Android? Or is it possible but no one made it till now? Or does it already exist and i am too dump to find it?

[Q] [LINE] Can't use SD card. Please confirm SD card settings

Dear All,
This is my desperate attempt after days of googled with a dead end.
Recently, out of nothing i have encountered a major error after years. It all of sudden. Bombarded with "google play service is stopped" then decide to reboot then never up again with "acore stopped working'' on the very first screen after samsung logo where you have unlock the screen.
I did wipe data/factory reset. All good. reinstalled all essentials. SuperSU and Rootchecker report im still rooted. Then noticed LINE app (by Naver) has a bizarre behavior. All image related operations is not working with message "Cant use SD card, please confirm SD card settings"
All other chat messengers all working flawlessly (BBM, Whatsapp, you name it) but this one. To be detailed, affected operations are downloading stickers, themes, chat image attachments, chat photos wont came out, trigger camera, attach/send photo..
Submit a ticket to Naver but returned with they have no support for rooted device.
Device detail:
N7100 4.4.2 (rooted)
SuperSU / Knox disabled
modified platform.xml (extsdcard write access)
Failed Attempts:
- format ext SD card from inside, issue still exist
- install / reinstall LINE app, issue still exist
any kind of idea/helps would greatly appreciated as most of my contacts and communication are mainly using this app. I hope you guys have knowledge to be shared for pinpoint the issue based on the error message above. I believe the solution can be a great value as there are currently none in the net.
Thanks

try to apply kitkat sdcard fix
click

I have the Xperia Z3 running on Lollipop.
Same issue, all apps such as whatsapp, fb, etc can access the SD card except for line.
The error message when trying to send a photo to someone in Line is "Can't use SD card. Please confirm SD card settings"
Reinstalled the app several times, unmounted and remounted the SD card, even moved the app to the SD card with the app itself still working fine. But still cannot send or receive photos or download stickers.
Also applied the suggested that sd card fix even though it wasn't really needed since all other apps can access the SD card just fine..anways it didn't help.
Any other ideas?
Oh yeah, even tried installing a Line version which was 6 months old - didn't help either.

I have the exact same issue after a full wipe and re-flashed custom ROM. The naver LINE app have the same issue as mentioned above. All other apps functions normal. Anyone found a solution to this yet?

Hi. I've encountered a similar problem recently. The interesting thing is that my telephone does not have SD card at all. So my first thought was that the problem is in permissions or cache.
I checked the permissions - app had full access.
Then I cleared programm cache on my phone. both inner memory cache and telephone memory cache (at least that's what they are called in my native language)
After that I tried to upload the image, yet it gave another error. something like: "cannot perform the action now, try again later"
I was quite short on the inner memory on my phone (around 70 MBs free), and thought it can be the problem. I deleted the biggest app and was able to upload the screenshots again.
Probably worth mentioning: I did not reinstall the Line app.
My device:
Telephone called ImSmart C471. China at it's best. Assembled in Ukraine though, company called Impression.
Android 4.4.2

In the latest build, Line apk cant send photo from internal/sdcard..it said line cant use sdcard..?

i had the same problem when i moved to new phone ( Xiaomi Mi4 ). I solved that. Just find the application permission setting in application manager. Try to find permission to stroarge. Change the permission to allow. That's it. That worked for me.

where's the settings?

I can't find any setting for permission to storage from the application manager, is there any? did I overlooked?

Try updating the app in play store. I had the same issue but solved with the updated version.

I had the smale problem. I deleted some pictures and videos and then restarted the phone. Works like magic

Xposed for A7 2016

Hello Sirs
I want to install xposed on my (SM-A710FD) phone which is 5.1.1 android

This is a 2017 series.

For what do you need Xposed? I have tried it on my tablet and there is little to no use for Xposed. Maybe I change my mind if you tell me some good modules.

The problem with Xprivacy is that it is quite hard to understand. There are no community driven settings like in uBlock Origin (adblocker for pc). Nor there are options for temporary allowance. Besides, Android 6 already has permissions per app.

What is there to understand? My 13 year old nephew managed to set it up.
Android 6 does not offer this many options. Can you stop an app getting your IMEI or Phone serial details? Why does an app need your IMEI?
It comes with default settings such as location (Christmas island) IMEI 00000000 etc.
1-Install the correct version of Xposed for your device.
2-Install Xprivacy app.
3-Launch, allow Root, click on Template and set each permission request to block.
4-Reboot phone, launch Xprivacy, see if template has been applied.
5-Install an app or game. You'll get notification from Xprivacy with template applied.
6-Allow the permissions that the app needs. Eg Firefox browser needs Internet,Network,IPC,System allowed to work.
For games I don't allow any permissions and it still works.
If you need to allow temporary permissions just launch Xprivacy and turn it off for that app.

Blocking everything isn't a solution as apps need for example the shell and filesystem to store setting files at first startup.
There are sub permissions which are quite unclear if you can disable them. Plus, after every app update the new nag screens come up and apps might not work anymore. You say Firefox needs ABC. But how to know what each app needs at bare minimum?

You are not blocking everything for ever.
The template is set to block all at first app install so that the app doesn't get access to sensitive information that it doesn't need. You can deny the sub permissions if you want but this can effect how the app behaves. You don't need to mess with the sub permissions.
At every app update Xprivacy will re apply the permissions that you've already set for that app. You don't need to re do it.
As to allowing Shell and system at first start up go back into Xprivacy and allow these permissions/ re launch app.
The ABC for Firefox was an example. Firefox is a web browser so obviously it needs data access. Root Explorer obviously needs Shell, and System and so on.It is easier then you think.
Once you have setup all the permissions for your apps and they are working Xprivacy has a function to save or export your setup. So that if you change ROM all you need to do is import it and it will do the rest.
If you read the link I included all the answers to your questions are there. Google is useful too.

[Privacy] Modifying Permissions for System Apps

Hi there,
For the benefit of increased privacy, how can I modify the permissions (such as microphone, camera, body sensor access) for system apps, like System UI or Accessibility etc?
I wish to have access to such permissions to choose what I feel is required/necessary.
My phone (G985F) is rooted with Magisk and I have already removed/frozen a bunch of bloatware but like I mentioned would like to revoke some permissions for 'system apps'.
Please can someone assist me or point me in the right direction, thanks heaps.
Andy.

Thanks for your reply. I think you may have misunderstood what I'm asking here, while what you've shared is relating to modifying app permissions installed on the phone, it does not allow modification of 'system app' permissions as I stated I'm trying to do in my post. Currently, upon attempting to do this for say System UI (a system app/service) for example - I am unable to revoke microphone permissions due to it being greyed out and saying "Device needs this permission to operate".

Its probably because those permissions are a must for the phone to operate. Somethings are just needed to make a device work.

Not exactly what you want but Package Disabler Pro can disable system apps completely without root, I tried disabling certain permissions but couldn't find a way, just to disable it completely

Theres also CCSWE app manager which also has the ability to disable system apps and i think individual processes within the app, if you know exactly what your looking for.

Question My banking application will not allow me to enter that I am using Whatsapp PLUS

Hi.
Today I needed to pay something through my banking application, but the application did not allow me access because it detected malicious software on my phone and it is Whatsapp PLUS, which I have to uninstall in order to enter the banking application.
What should I do now if I use Whatsapp PLUS all the time, but at the same time I need access to my banking application?
How does a banking application detect that I am using an illegal Whatsapp Plus application?
Is there a way around it?
Thanks a lot.
And for info root I have over Magisk.

This might seem trivial, but have you tried revoking the "Get info about installed apps" permission?
Most apps use this to index all your apps and check for so-called "malicious" package names.

What should I do?

Even if I freeze WhatsApp via titanium backup, the bank's application still notifies me that there is malicious software on my device - WhatsApp.
That I should just uninstall it.

go to your banking app's "App Info" page, under permissions, look for "Get info about installed apps" and if it is "Allowed", change it to "Deny"
this is assuming you are on MIUI. I'm sure other ROMs also have a similar permission.

What is the package name of your whatsappPlus app? You should find it in the "App Info" page for the app. Should be something like "com.whatsapp"

There is no such setting about allowing the installation of applications under permissions - allowed / deny

In that case you either modify the app itself - use apk editor to decompile app , edit manifest.xml and remove permissions like "query all packages" from it . Compile the app and run it again. This might work but if app is protected in some way that it detects modification you might get banned from it or worse :/
Other way is to isolate WhatsApp Plus by using tools like virtual xposed - basically a virtual container. You can install WhatsApp in there and it shouldn't cause any issues but I'm not sure you'll be able to receive notifications... ( You can try installing bank app in there instead but I'm not sure how that'll work... Either it will detect root/xposed or the container itself will allow querry all packages to seep through into main os - this depends on whether virtualxposed has declared permission for querying packages or not )
Third option is probably the best one - Uninstall and use web browser to access banking.

maybe whatsapp plus is indeed malicious
use malwarebytes for android to check whether whatsapp plus is malicious or not
